Magetic softening of Young's modulus of amorphous Fe90Zr10
Abstract
The Young's modulus and the internal friction of amorphous Fe90Zr10 alloy were measured near the Curie temperature using the vibrating reed technique. The modulus shows softening around Tc≈ 227K and the internal friction undergoes drastic increase at Tc. It is found that both the Young's modulus and the reciprocal of internal friction are inversely proportional to the magnetic susceptibility in the paramagnetic phase.
